It’s been one week since we surgically implanted PIT tags into 36 Frecklebelly Madtoms. See image below.

Today, undergraduate student (Rick Campbell) and postdoc (David Schumann) returned to Private John Allen National Fish Hatchery to check on the fish.

So far, so good. Only one fish has died as a result of the procedure and every other fish has retained their tag. The incision wounds have healed rapidly and many are hardly noticeably after only seven days!
